What is it about?
Hydrogen fuel produced from water is considered a promising way to alleviate heavy dependence on fossil fuels which have been blamed to cause global warming. Sulfur-Iodine Thermochemical Cycle process is more efficient in term of thermal energy conversion than the conventional water electrolysis. The paper describes how the Bunsen Reactor (which is one of the main components in the plant) can be modelled, and the model can be subsequently used to develop a control strategy for reactor with aid of the multi-scale control (MSC) scheme. The MSC scheme is a new method which aims to control a given system by providing good control of several sub-systems (which are multi-scale in nature) making up the overall system.

Why is it important?
Good control system is crucial in any man-made dynamic system. In this case, it is important to run the complex nonlinear Bunsen Reactor in an optimum way, which in turn shall reduce the operating cost as well as increase safety standard.
Perspectives
The proposed multi-scale control scheme can be used to control the entire Sulfur-Iodine Thermochemical Plant. The work is ongoing. Part of the research is to produce a new controllability analysis which can be used to describe the stability and performance trade-offs more objectively and many existing controllability methods.
